JOURNAL-BEARING.

SPECIFICATION forming part of Letters Patent No. 710,466, dated October7, 1902.

Application filed December 16, 1901. Serial No. 86,033. (No model.)

To (IIZZ whom it may concern:

Be it known that I, CHARLES H. KEENEY, a citizen of the United States,residing at Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inJournal-Bearings, of which the following is a specification.

This invention relates to a ring lubricating j ournal-bearing.

The object is to provide a very simple, durable, and efficient bearingof this type which may with equal facility be set upon a foundation orfloor or be suspended from overhead timbers or ceiling, as thecircumstances require.

This bearing is more particularly designed for supporting the journal ofthe fan of an exhauster or blower; but it is also very serviceable forsupporting the journals of other high-speed machines.

The bearing has a chair formed of brackets that may be fastened to afloor or to a ceiling. The casing is formed inltwo parts boltedtogether, and each part contains one-half of the babbitt-box. one partof the casing is bolted between the chair-brackets. Between the casingand the box of each section is a chamber for containing the lubricant,and through the casing into each chamber is a threaded perforation. A

lubricant-cup is screwed in the upper of these perforations, and adrip-cock is screwed in the lower perforation. The boxes near each endare cut out or grooved entirely around the journal in order to receivethe lubricant-rings.

Figure 1 of the accompanying drawings shows aside elevation of a bearingthat embodies the invention in the position occupied when it is setupright upon a floor or other support, a portion being broken away to{show the interior. Fig. 2 shows an end elevation of the same bearing inits upright position with a portion cut away on the plane indicated bythe broken line 2 2 of Fig. 1. Fig. 3 shows a side elevation of the samebearing in the position occupied when suspended from a ceiling, and Fig.4 is an end elevation of the bearing in its suspended position withparts out in section on the plane indicated by the broken line 4 4 ofFig. 3.

The chair is formed of two similar angular A lug projecting frombrackets 5, eachof which has a base for attachment to afloor, ceiling,or other support, and an car through which passes the bolt 6, whichholds the lug 7 between the chair parts. The lug 7 is integral with acasting 8, to which the casting 9 is secured by bolts 10, these castingsforming the casing. In each of these castings and integral therewith isa similar semicylindrical box part 11,which is recessed to receive thebabbitt 12. Between the easing and the box of each section is a chamber13. The box is cut away so as to form a narrow opening 14 entirelyaround the journal near each end. In each opening and loosely restingupon the journal is a ring 15, that has an inner diameter that isconsiderably larger than the diameter of the journal. These narrowopenings completely encircle the journal, so that the ring, whether thebearing is upright or reversed, will loosely rest upon the journal.Through the casing part 9 is a perforation 16,'and through the casingpart 8 is a perforation 17. When the bearing is set upright, as shown inFigs. 1 and2, an oil-cup 18 is screwed into the upper opening 16 and adrip-cock 19 is screwed into-the lower opening 17. When the bearing issuspended from above, as shown in Figs. 3 and 4, the oil-cup is screwedin the opening 17 of the part 8 and the drip-cock 19 is screwed in theopening 16 of the part 9.

The chair which supports this bearing may with equal facility be boltedto a floor, standard, or other foundation, or be bolted to a ceiling,overhead timbers, or other depending support. Whichever way the bearingis placed, whether upright or reversed, there is always alubricant-chamber below the bOX and the rings will always loosely restupon the journal and hang down into the lubricant-chamber. Thelubricant-cup is screwed into the perforation through the casing partthat is uppermost and the drip-cock is screwed.

into the perforation through the casing part that is lowermost. It isonly necessary in reversing this bearing to change the relativepositions of the lubricant-cup and the dripcock. The interiorconstruction is such that the bearing-surface, the lubricant-chambers,and the rings are always the same in whatever position the boX isplaced.

This bearing, which has few parts and is very simple in construction, isserviceable for supporting the journals of the fans of eX- hausters andblowers, which are driven at high speeds and which are usually placed ina factory or mill in the most available space which is left aftercompletion, and this space sometimes permits the machine to be placedupright and sometimes to be suspended from above.

This invention provides a ,very durable and efficient bearing ofapproved type which can be applied to the shaft of a fan at the factoryand sent out Without regard to the position the fan must occupy when setup in the place where it is to be used.

I claim as my invention 1. A journal-bearing consisting of a chairsupporting a casing formed of two similar parts, each casing part havinga bearingsur face with a chamber between the casing and thebearing-surface, a perforation through the casing into the chamber and atransverse opening entirely through and completely separating thebearing-surface into sections,

a ring loosely located in the transverse opening, a lubricant-cupsecured in the top perforation through the casing, and a drip-cocksecured in the bottom perforation through the casing, substantially asspecified.

2. A journal-bearing consisting of a chair formed of two brackets, acasin g consisting of two similar parts, one casing part having a lugpivoted between the chair parts, and each casing part having a babbittedbearing-surface with a chamber between the casing and thebearing-surface, a perforation through the easing into the chamber andtwo transverse openings entirely through and completely separating thebearing-surface into sections, a ring loosely located in each transverseopening, a lubricant-cup secured in the top perforation through thecasing and a drip-cock secured in the bottom perforation through thecasing, substantially asspecified.
